Had a comfortable one-week stay at Cosy Soi Silom 3 Condo # 5 with efficient wi-fi / internet connection. Enjoyed the view at night from the balcony. The accommodation is close to BTS stations: Chong Nonsri and Saladaeang. Plenty of eating places nearby or in the surrounds. A reliable currency exchange place (Super Rich, located within Silom Complex) is approx. ten minutes walk.
Will consider staying here or one of K's properties if / when next travelling to Bangkok.
